Site Investigation Section

The Florida Department of Environmental Protection (DEP) Site Investigation Section (SIS) conducts environmental assessments throughout Florida. These assessments are vital to protecting the state’s residents and visitors, as well as our fragile environment. Assessments typically emphasize soil and groundwater impact determinations. Groundwater produced from aquifers provides almost 90 percent of Florida's population with fresh, clean drinking water. Sites requiring assessment are prioritized and referred to Site Investigation staff by the DEP district offices. Staff also provide technical support and assistance to various law enforcement agencies to assist in the investigation of environmental crimes.

Since its inception in 1982, Site Investigation staff have conducted or supervised environmental assessments at more than 750 sites. Examples of sites assessed include electronic manufacturing facilities, dry cleaning facilities, maintenance yards, printing facilities, chemical storage tanks, agricultural fields and golf courses. Staff also conduct large-scale investigations to determine the sources of groundwater contamination affecting public and private supply wells.

Site Investigation personnel consist of scientists, licensed monitor well drillers and technicians. To support various assessment needs, SIS maintains and operates a Geoprobe Model 6600 direct push unit with hydraulic profiling and electrical conductivity capabilities, as well as a Geoprobe Model 5410 direct push unit. Overflow assessments are conducted by licensed environmental firms and include all phases of study. Subcontracted services such as mobile laboratory, borehole geophysical and ground penetrating radar are common. Contracted work is directed by experienced DEP contract managers.

The State-Owned Lands Cleanup Program is included within the Site Investigation Section. The program is funded by the Florida Legislature to address potential health-related and environmental issues on state-owned properties. The program began in 2001 and is available to all state agencies. Site Investigation Section contract managers oversee all activities, which are generally conducted by private environmental firms. Almost 400 areas of concern on 85 state properties have been assessed.
